Abstract

L'invention concerne un dispositif de mesure de la torsion d'un corps. Ce dispositif comprend des première et seconde parties d'agrafe, chacune présentant une partie centrale et deux branches dépendant de ladite partie centrale. Chaque branche comprend, adjacente à l'extrémité libre de la partie centrale, une rainure ou une projection conçue pour venir en prise avec une projection ou rainure (14) correspondante formée dans le corps (16). Ainsi, la partie d'agrafe est montée sur le corps attaché de manière rotative à celle-ci. Un pont est relié à la partie d'agrafe. Ledit pont est moins rigide que les parties d'agrafe. La torsion du corps entraîne le déplacement rotatif associé des parties d'agrafe qui permet de dévier proportionnellement le pont. Des moyens tels qu'un dispositif d'onde acoustique de surface (15) sont fournis pour mesurer la déviation du pont afin d'obtenir une indication de la torsion qui produit la déviation du pont. Ledit dispositif peut également être utilisé à l'intérieur d'un corps creux.
